SWING.

SPECIFICATION forming part of Letters Patent No. 596,108, dated December28, 1897.

Application filed March 20, 1 8 9 '7.

To all whom, it may concern.-

Be it known that I, MAX GANTER, a citizen of the United States, residingat Buffalo, in the county of Erie and State of New York, have invented anew and useful Improvement in Swings, of which the following is'aspecification.

This invention relates more particularly to portable indoor swingsdesigned to be suspended between a pair of uprights, such as the jamb orsides ofa doorway.

The object of my invention is the production of an inexpensivesupporting device for such a swing which can be readily and reliablysecured in place without the use of nails, screws, glue, or otherfastenings that mar or mutilate the door-jamb.

In the accompanying drawings, Figure l is an elevation, partly insection, showing my improved supporting device in position across adoorway, with a swing hung therefrom. Fig. 2 is a fragmentary verticallongitudinal section of the device on an enlarged scale. Fig. 3 is afragmentary top plan View thereof on an enlarged scale. Fig. 4 is ahorizontal section in line 4 4:, Fig. 2.

Like letters of reference refer to like parts in the several figures.

A A represent a pair of uprights between which the swing B is suspendedand which may be the sides or jamb of a door-frame, as shown in thedrawings.

0 is a horizontal supporting-pole from which the swing is suspended andwhich is provided at each end with a pair of wedges D E, whereby thepole is clamped between the jamb or uprights A. The inner wedges D arerigidly secured to the. ends of the pole, so as to carry the pole, whilethe outer wedges E bear loosely with their vertical rear faces againstthe door-jamb and with their inclined front faces against thereversely-inclined faces of the inner wedges D. The inner wedges arefree to slide vertically on the outer wedges, so that a downward pull onthe pole causes the inner wedges to force the outer wedges against thejamb, thereby tightly clamping the pole between the sides of the doorwayand reliably holding it in place without the use of nails, screws, orother fastenings which disfigure the jamb. By this construction theSerial No. 628,550. [No model.)

pole is secured more tightly the greater the weight suspended from thepole.

The outer wedges are preferably permanently attached to the innerwedges, so as to keep the parts of the device intact and facilitate theapplication of the device to a suitable support. For this purpose thewedges at the same end of the pole are connected bya screw or bolt f,passing through a vertical slot f, formed in the outer wedge and throughthe inner wedge and entering the end of the pole, as shown in Figs. 2and 4, the slotted wedge being recessed on its back, as shown at f tocountersink the head of the connecting-bolt. In order to increase thefriction between the jamb and the outer wedges E, the latter areprovided at their back with a facing g of canvas or similar roughmaterial. This facing also serves to cover the recess and slot of thewedge. To keep the wedges of each pair in their proper relativeposition, one of the wedges is provided with one or more vertical tenonsh and the other is formed in its opposing face with grooves h forreceiving these tenons, thereby preventing the wedges from turning ortwisting on each other.

The pole may be made in a single continuous piece, if desired; but it ispreferably made of two adjustable sections, as shown in Fig. 1, so thatit can be lengthened or shortened to fit different-sized doorways. Inthe construction shown in the drawings the polesections areconnected bya sleeve or tube I, in which they are adj ustably clamped by setscrewsIn order to relieve these screws when the sections are partly drawn out,the vacant space in the sleeve between the inner ends of thepole-sections is filled by cylindrical blocks j. By the use of thesefillingblocks the pole is rendered practically continuous and the thrustis received by the end wedges instead of the set-screws.

The pole is provided with hooks or other suitable attachments 7a, withwhich the rings Z of the suspension-cords Zof the swing are engaged, asshown in Fig. 1.

In applying the pole to a doorway the outer wedges E are slid downwardlyon the inner wedges to the limit of their movement, and the pole is thenadjusted in length so that the outer wedges touch the door-jamb. The

outer wedges are then driven upward with a mallet, and the pole is atthe same time held with one hand and gently pulled downward, the polebeing securely clamped in place by the time that the wedges aretightened. The wedges should be located about two inches below thelintel or top of the doorway after the wedges have been tightened. Aftersecuring the pole in position the swing is suspended therefrom. In orderto remove the pole, it is only necessary to press the same upwardvigorously, when the wedges will be loosened.

Myimprovement is not only extremely simple, but can be quickly appliedand released without inutilating the part to which it isattached,renderin g the device especially advantageous for indoor use.

I claim as my invention 1. A support for portable swings, consisting ofa pole, inner wedges secured to opposite ends of the pole, outer wedgesbearing with their inner faces against the inner wedges, and adapted tobear with their outer faces against a pair of uprights, and connectionsbetween said wedges which permit the outer wedges to slide on the innerwedges, substantially as set forth.

2. A support for portable swings, consisting of outer wedges adapted tobear against a pair of uprights, and a pole provided at opposite endswith wedges which bear against said outer wedges, the wedges at the sameend of the pole being provided with an engaging tenon and groove wherebythe same are retained in alinelnent with each other, substantially asset forth.

A support for portable swings, consisting of a pole provided at oppositeends with inner wedges, outer wedges bearing against said inner wedgesand each provided in its front face with a vertical slot and in its rearside with a recess opening into said slot, screws or bolts passingthrough the slotted wedges and entering the inner wedges, each of theouter wedges having 011 its rear side a facing which covers the slot andrecess thereof, substantially as set forth.

4. A support for portable swings, consisting of a pole composed ofadjustable sections each provided at its outer end with a pair ofcooperating wedges, a sleeve connecting the inner portions of thepo1e-sections, and fillingblocks arranged in said sleeve between theadjacent ends of the pole-sections, substantially as set forth.

W'itness my hand this 16th day of March, 1897.

MAX GANTER.
